Specification of Letters Patent.

Patented June 30, 1914:-

Application filed March 10, 1913. Serial No. 753,426.

To all whom it may concern Be it known that I, HAnveY P. SPENCER, acitizen of the United States, residing at Des Moines, in thecounty ofPolk and State of Iowa, have invented a new and useful Candy-Puller, ofwhich the following is a specification.

The object of my candy pullerof simple, durable and lnexpensiveconstruction.

A further object is to provide such a device provided with a shaftcarrying two arms, spaced apart from each other, and of suchconstruction and arrangement that when said. arms are rotated they tendto corn stantly work the candy toward the central point by wrapping itaround the arms.

A further object is to provide in connection with said arms a guidedevice for keeping the candy on said arms and for assisting in workingit toward such central point.

A further object is to provide, in addition to the said pair of arms,another arm, rotated from a shaft and designed to pass in one point ofits rotation close to but outside of circle of rotation of said pair ofarms, the last described arm being adjustable so that it may be made topass closer to or farther from said rotating pair of arms. My inventionconsists in certain details, in the construction, combination and arrangement of the various parts of the device, whereby the objectscontemplated are attained, as hereinafter more fully set forth, pointedout in my claim and illustrated in the accompanying drawings, in whichFigure 1 shows a top or plan view of a candy pulling machine embodyingmy invention. Fig. 2 shows a side elevation of the same. Fig. 3 shows asectional view of the clutch device.

In the accompanying drawings I have used the reference numeral 10 toindicate generally the frame which supports the operative mechanism ofmy improved candy pulling machine.

I provide two shafts 11v and 12 mounted on said frame 10 in suitablebearings. Rotary motion may be imparted to said shafts by any suitablemeans. In the drawings I have shown on the shaft 11 belt pulley 13 andsprocket wheel 1 1. I provide a counter shaft 16 on which are mountedsprockets 17 and 18. A chain 19 travels on the sprockets 1 1 and 17, anda chain 20 travels on the sprockets 18 and 15.

invention is to provide a I preferably provide similar candy pullingmechanism on eachside of my improved machine. I shall thereforedescribed such mechanism as applied to one side of the machine only. Thearm 21 is provided with a bearing 22, which is rotatably mounted on oneend of the shaft 12.

It is important that means he provided whereby each arm 21 may bereadily and easily thrown into and out of gear with the shaft 12; Foraccomplishing this purpose I have provided the following means.

Formed on the bearing 22 opposite the arm 21 is an approximatelycylindrical extension 23, in' which is a cylindrical opening 31,communicating at its inner end with the opening which receives the shaft12. The outer end of the opening 31 is contracted at 32. Slidablyreceived in the openings 31 and 32 is a stem 33, on which is a head 3 1.Mounted on the stem 33 near the inner end thereof is a collar 35.Mounted on the stem 33 between the collar 35 and the contracted portion32 of the opening in the extension 23 is an expansible coil spring36,designed to hold the stem 33 at the inward position of its movement.In a shaft 12 a. recess 37 designed to receive the end of the stem 33.In the outer end of the extension 23 is a transverse slot 38. Extendingthrough the stem 33 near the head 34- is a transverse pin 39. 'When thestem 33 is drawn outwardly, its inner end is withdrawn from' slot oropening 37, and by rotating the stem 33 slightly the pin 39 may becaused to rest against the outer end of the extension 23. The stem 33may be rotated until the pin 39 registers with slot 38, when the spring36 will force the stem 33 inwardlyand cause the end of said stem toenter the opening 37 as the shaft 12 rotates, thereby causing the arm 21to rotate with said shaft 12. The importance of some means foraccomplishing the purpose of the mechanism just described will behereinafter more fully set forth.

The arm 21 is provided with a longitudinal elongated slot 241. Anotherarm J) is adjustably secured to the arm 21 by means of bolts 26, andnuts 27. On the outer or free end of the arm 25 is a. laterallyextendin'g curved arm 28 clearly shown in Fig. 2.

On each end of the bar 29 is an outwardly extending arm 30. The arms 30are preferably curved as shown in Fig. 1 in opposite directions. Theyare also preferably so mounted on the bar 29 that when the bar areinclined 29 is in a horizontal position as shown in the lower part ofFig. l, the said 3O lie in substantially parallel planes. In oth'er 71.i... Y., is in a horizontal position is curved frdm the bar upwardly andoutwardly and then? downwardly and' outwardly (see' left ha'nd arm 30 inFig. 2) and'theothcr arm 30$.is

curved downwardly and outwardly, and then upwardly and outwardly (seeright hand arm 30 in Fig. 2). The arms 3Q are also preferably so mountedonthe bar 29 that the left hand arm as'shown in l ig.2 in clinesupwardly toward a vertical plane in which shaft-l1 lies, and the righthand arm 30 inclines downwardly and toward the said plane.

Secured to the frame of my machine near the upper part thereof, on theend adjacent to the shaft 11 are laterally extending arms 40. Carried byeach arm 40 is a pair; of parallel arms l1 extending toward the arms 30.In each of the arms ll I provide a plurality of openings 42. Selectivelymounted in the openings l2 are guide. pins 43, which downwardly Y andtoward each other.

I willnow describe the practical operation of my improved candy pullingmachine. It will be understood that the gear mechanism for operating thevarious shafts may be varied as desired and'that the gear mechanismshown is simply for the purpose of illustration. Assumingthat the pulley13 is connected with asuitable source of power such as an electricmotor, or a gasoline engine, I place abatch of candy onjthe arms 30.With most of the candies which are pulled, it is highly desirable toworlethe candy for a short time on the arms 30 before the arm 28. isoperated. The candy does not stick or pull well on the arm 28 if thatarm is operated as'soon as the candy isput on the machine I disconnectthe arm 21 with shaft 12 by drawing the stem 33 outwardly and rotatingit until the pin 39 rests against the outer endjof the exten sion23where1t is held by fr ction. I can then worlrwiththe candy on thearms'30 without danger of being strucl by the arm and the candy willbe workedby the arm 30 for a short time, until it. is in condition to be pulledby the arm 28. After the candy has been worked by the arms30 for a shorttime, I turn the stem 33 until the pin 39 is received in the slot'38 andthe end of the stem 33 enters the opening 37. The

arms 30 rotate in the direction "indicated by the arrow above said armsin' Fig. 2, and the arm 23 rotates 1n the direction indicated "by thearrowon' the wheel 15 in Fig. 2.1 As the arm 28 passes the arms 80 itstrikes the ball. of candy" and in its further rotation pulls, the candyinto a long string. The rotation of the arms 30 also stretches the candyinto a thinner string until the arm 25 is extended away from the shaft12 in the opposi't' directi on fioiii the shaft 11. As the rotation ofthe arm 28 continues, the arms 30""wind the string of candy into a ballagain. This operation is continued until the artery is Pulled.

-I believe-that my candy pulling machine produces better results thanany other machine for the following reasons: The arms 30, aremountedcomparatively close together 7 on thelbar 29, equal distances shaft 11,W nd a said 'ar'm's so tQlb revolved rapidly with out centrifugal'forc'e' deflecting the candy being'worked, and such deflection wouldresult were said arms mounted farther apart and revolved atfthef'samespeed Existing candy machines with a similar double arm arrangement have'the arms 'mounteda suflicient di s tance apart to" allowanotherfrevolviiig arm tofpafss in i between saidarms, or to stretchcandy over a stationary placed between: the moving arms, necessitatingrelatiyely slow speed.

Itis one of the ,purposes of,the candy pulling machine to thoroughlyaerate the candy. arms30' and arm s 28'ihave thejcandy pulledinto a longStraig ts above described, the action "of arms 30.

The surface of candy when pulled'iiito' a string is more or less rough;containing interstices or aircells, The arms ISO- quickly 'i'ollthe string of candy into a ball,,the,air the intersticesor air cells is caught and retained inithefolds ofthe jcandyf, and the continuous rapid pulling action of arms EQOdan dthe intermittent pulling action of arin28 forced into caught andretained, thereby producing rapid and thorough aeration.

'Iam aware that there are machines now i use a n w; mov tertwin ng arms,or one or more stationary armsintersecting the pathpf one or morerevolving or reciprocating arms, but I prefer to use the comparativelyrapidly rotating arms 30 they are preferably 30,... It. will'be and thesingle rotating arm 28, the last named arm 28 not intersecting thecircle of rotation of the two first named arms 30. My machine is verysimple of construction, can be built cheaply and durable and operated inless space than the larger intertwining arm machines.

Many variation made he made in the details of construction of my candypulling machine without departing from its essential features.

It is my purpose to cover by this application for patent any variationsin the structure of my device coming within the scope of the appendedclaims.

I claim as my invention,
